Serum testosterone is a potential marker to distinguish between indolent and aggressive prostate cancer (PCa). The present study aimed to investigate whether low levels of total serum testosterone at diagnosis were associated with aggressive PCa and poor clinical outcomes. In total, 762 non-Hispanic Caucasian men with previously untreated PCa were recruited from The University of Texas MD Anderson Cancer Center (Houston, TX, USA). Patients were categorized into three groups based on their total serum testosterone levels according to clinical guidelines [low (<230 ng/dl), intermediate (230-350 ng/dl) and normal (>350 ng/dl)]...

Tumor-to-meningioma metastasis (TMM) is a fairly uncommon phenomenon. Only 7 cases of prostate cancer with TMM have previously been described in the literature. The present study aimed to report a case of prostate cancer TMM, and to discuss the relevant clinical and neuroimaging aspects of this condition. A 68-year-old patient presented with headaches, poor visual acuity in the left eye and ipsilateral eyelid droop 3 years after a Simpson II resection of a left sphenoid wing meningioma. Computed tomography revealed a hyperdense area suggestive of a recurrent left sphenoid wing meningioma...

MicroRNAs (miRNAs) are non-coding small RNAs that are master regulators of genic expression and consequently of many cellular processes. But their expression is often deregulated in human tumors leading to cancer development. Recently miRNAs were discovered in body fluids (serum, plasma and others) and their levels have often been reported to be altered in patients. Circulating miRNAs became one of the most promising biomarkers in oncology for early diagnosis, prognosis and therapeutic response prediction. Here we describe the origins and roles of miRNAs, and summarize the most recent studies focusing on their usefulness as cancer biomarkers in lung, breast, colon, prostate, ovary cancers and melanoma...

BACKGROUND: Progressive loss of muscle mass is a major characteristic of cancer cachexia. Consensus definitions for cachexia provide different options to measure muscle mass. This study describes the effect of different methods to determine muscle mass on the diagnosis of cancer cachexia. In addition, the association of cachexia with other features of cachexia, quality of life, and survival was explored. METHODS: Prior to chemotherapy, cachexia was assessed by weight loss, body mass index, and muscle mass measurements, the latter by mid-upper arm muscle area (MUAMA), computed tomography (CT) scans, and bio-electrical impedance analysis (BIA)...

Microfluidics is considered an important technology that is suitable for numerous biomedical applications, including cancer diagnosis, metastasis, drug delivery, and tissue engineering. Although microfluidics is still considered to be a new approach in urological research, several pioneering studies have been reported in recent years. In this paper, we reviewed urological research works using microfluidic devices. Microfluidic devices were used for the detection of prostate and bladder cancer and the characterization of cancer microenvironments...

Both cholesterol levels and the use of statins have been described to influence the development and prognosis of prostate cancer (PC). In this retrospective, cross-sectional analysis of consecutive cases from a tertiary referral center we evaluated an association between hypercholesterolemia (≥5.0mmol/l), the use of statins, and advanced/aggressive PC in 767 men with histologically confirmed, clinically localized PC awaiting radical prostatectomy. We found that patients with HCE (n=287, 37.4%) had a significantly higher incidence of poorly differentiated PC (Gleason score ≥7b, 81...

Prostate cancer is the second highest cause of cancer mortality after lung tumours. In USA it affects about 2.8 million men and the incidence increases with age in many countries. Therefore, early diagnosis is a very important step for patient clinical evaluation and for a selective and efficient therapy. The study of miRNAs' functions and molecular mechanisms has brought new knowledge in biological processes of cancer. In prostate cancer there is a deregulation of several miRNAs that may function as tumour suppressors or oncogenes...

AIMS: The reported long waiting times for cancer patients have mostly been related to prognostic outcome and less to patient-related experience to outcome. We assessed waiting times for patients with cancer of the breast, prostate, colon or rectum in Sweden. METHODS: The median time from referral to start of treatment was assessed using data from clinical cancer registers for patients who received curative treatment during 2011, 2012 and 2013. RESULTS: The median overall waiting time in different counties ranged from 7 to 28 days for breast cancer, from 117 to 280 days for prostate cancer, from 27 to 64 days for colon cancer and from 48 to 80 days for rectal cancer...

We hereby present the case of a 55 years old patient with clinical diagnosis of high-risk prostate cancer T2bN1Mo Gleason 9 (4 + 5) treated with androgen deprivation therapy and external beam radiotherapy. Despite treatment, castration levels were not achieved and clinical progression was evidenced by the appearance of bone metastases and progression of PSA. After several hormonal treatments without any PSA or testosterone response, surgical castration was performed by bilateral orchiectomy. The pathology results showed an incidental Leydig cell tumor in the right testicle...

Accurate analysis of specific biomarkers in clinical serum is essential for early diagnosis and treatment of cancer. Here, a surface-enhanced Raman scattering (SERS)-based immunoassay, using magnetic beads and SERS nano tags, was developed for the determination of free to total (f/t) prostate specific antigen (PSA) ratio to improve the diagnostic performance of prostate cancer. To assess the clinical applicability of the proposed method, SERS-based assays for the simultaneous detection of dual PSA markers, free PSA (f-PSA) and complexed PSA (c-PSA), were performed for clinical samples in the gray zone between 4...

BACKGROUND: Analysis of systematic 12-core biopsies (SBx) has shown that African-American (AA) men tend to harbor higher risk prostate cancer (PCa) at presentation relative to other races. Multiparametric magnetic resonance imaging (mpMRI) and MRI-ultrasound fusion-guided biopsy (FBx) have been shown to diagnose more intermediate- and high-risk PCa in the general population; however, the efficacy in AA remains largely uncharacterized. We aim to evaluate the utility of FBx in an AA patient cohort...

BACKGROUND: While older age is associated with higher tumor grade, it is unknown whether comorbid disease burden has a similar, independent association. We sought to evaluate the impact of comorbid disease burden on tumor grade at diagnosis as indicated by biopsy Gleason score. METHODS: We conducted an observational cohort study of 1260 men newly diagnosed with non-metastatic prostate cancer from 1998 to 2004 at two Veterans Affairs Medical Centers. Multivariable ordinal and multinomial logistic regression were used to evaluate the association between Charlson Comorbidity Index score and biopsy Gleason score...

Multiparametric Magnetic Resonance Imaging (mpMRI) has added to the armamentarium for the diagnosis and surveillance for organ confined prostate cancer. Atypical small acinar proliferation (ASAP) and high-grade prostatic intraepithelial neoplasia (HGPIN) are premalignant prostatic lesions. The management of such lesions remains contentious, and the addition of mpMRI introduces further uncertainty given its ability to pick up indolent lesions and its use in targeted biopsy. We aimed to perform a comprehensive review of current evidence regarding ASAP, HGPIN and mpMRI to ascertain a consensus for a current management algorithm...
